Abstract: Construction projects are characterized as very complex projects, where uncertainties are part of it. Risk is an uncertain event or condition that, if it occurs, has a positive or a negative impact on one or more project objectives, such as time, cost, scope or quality. Risk management includes the process concerned with the conducting the risk identification, analysis, responses and management planning and control on a project The study aims at carrying out the risk assessment and management process in the construction of Bangalore Underground Metro project. At first, the risks associated with the project and also with the similar projects in past are identified and listed based on the historic reviews, interviews and literature review. A questionnaire survey is prepared for the risks that are listed and probability and impact of these risks on the projects are found out, and risks are prioritized based on the risk index score which forms the probability-impact matrix and risk register is formed. A schedule is prepared in Primavera P6, and then integrated with Primavera Risk Analysis (PERT Master) software which analyze the schedule for the risk events assigned to the activities and for the defined probability distributions and then schedule of the project is simulated using the Monte Carlo simulation for the both pre mitigated and the post mitigated analysis, and then results are compared. Response strategies are suggested for the moderate to higher priorities risks.
